HEATING BURNER.

Application filed November To all whom t may concer/n:

Be it known that I, HERMAN J. OSTEN- Donn, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented a new and useful Heating Burner, of which thefollowing is a specification.

This invention relates to improvements in heating burners suitable for afuel consisting of a mixture of air and natural or artiiicial gas, or amixture of air and hydrocarbon vapor.

One object of this invention is to produce an improved burner of thecharacter indicated which is remarkable for its great heatl ingeliiciency and also for its economy in the consumption of fuel in theattainment of said heating eliiciency. Y j n Another object is toprevent quivering or unsteadiness of the flames issuing from the burnerduring the operation of the burner.

Another object is tov produce a highly practical burner of the characterindicated which is simple and durable in construction, convenientlyinstallable within and remov able from a furnace and comprises simpleimproved means materially participatingin effecting more completecombustion.

With these objects in view, and to attain other objects hereinafterappearing, this invention consists in certain meritorious features ofconstruction, and highly important combinations and relativearrangements of parts, hereinafter described in this specifi. cation,pointed out in the claims, and illustrated in the accompanying drawings.

ln said draw-ings, Figure 1 is a top plan of a heating burner embodyingmy invention. Fig. 2 is a vertical section taken along' Y line 2 2 inFig. 1. Fig. 3 is a horizontal section taken along line 3 3 in Fig. 2.Fig. 4: isa vertical section taken' along any one of lines 1 -t in Fig.2. Fig. 5 is a vertical section taken along line 5 5 in Fig. 4, exceptthat'in Fig. 5 the handle-forming member illustrated in Figi is shown ashaving been swung upwardly. Fig. 6 is a vertical section taken alongline 6 6 in Fig. 5. Fig. 7 is a vertical section taken along line 7 7 inFig. 3. Fig.,8 is a horizontal section taken along line 8 8 in Fig. 2.Fig. 9 is a vertical section taken along line 9 9 in Fig. 2. Portionsare broken away in the drawings to reduce their size.

My improved burner (see Figs. 2, 3 andV 9) comprises a substantiallyhorizontal metal 17, i925. serial No. 69,597.

base A composed preferably of cast iron and preferably circularexternally as shown in dotted lines in Fig. 3; Said base has avscrew-threaded hole; 13 formedl centrally of and extending verticallythrough the base, and thedischarging end portion 14 of a fuelfeeding`pipe is threaded, atl said hole, into said base. Y y

The base A (see Figs. 2, 3 and 8) is .provided, at its topandsubstantially centrally between the hole 13'and the circumferentialedge of the base, ,with an upwardly projecting annular rib 15 which 'is'substantially concentric 'in relation tol said hole. Said base isprovided, at its topand about centrally between they rib 15 andthecir'cums4 ferential edge of the base, with an upwardly projectingannular rib 16 which is substantially concentric'in relation to andspaced from and surrounds 4the inner rib k15. By

the `hereinbefore described construction it will be yobserved that thebase. A extends laterally'of and outwardly from the outer rib y16 ofthebase allround said rib.

My improved burner see Figs. 2 and 3) comprises asubstantially verticalhollow met-al body B which is preferably composed of cast iron and has.an interior chamberf17 extending fromlthe base A upwardly into the upperand dome-shaped end portion 18 of said body. Said base constitutes thebot! Va bolt 20 anda nut 21which are applied in any approved manner.'The burner-body B (see Figs. 2 `and 8)-is provided, externally of thechamber 17, with a substantialy horizontal. circumferential flange 22spaced upwardly 'from lthe baseA and projectinglat# erally of andextending allround said body.

SaidV flange is preferably circular as'shown Y in dotted lines in Fig.8, and the body'B exf tends above said flange'preferably considerablyfarther than the distance between said flange and the base A. Said bodymeas-v ures considerably less inexternal diameter next above `and nextbelow said flange than said body measures in external diameter at itslower extremity, and preferably said flange measures less in .externaldiameter than the outer rib 16 of the base A.

The burnerbody B (see Fig. 2) comprises a downwardly flaring portion 24which is arranged under and vspaced downwardly from the flange 22,and'preferably said flaring portion of said body is spaced, at its upperend, considerably farther from the base A than from said flange andforms the greater portion of the body below said flange. The relativedimensions of the flange 22 and the downwardly flaring portion 24 of thebody B are preferably such that said flaring portion is arrangedsubstantially wholly under .said fla-nge.

The downwardly flaring portion 24 of the burner-body B (see Figs. 2 and3) has an annularly arranged series of lateral apertures 25 which arespaced circumferentially of said body and formed preferably under theinner portion of the flange 22 and preferably spaced farther from thebase A than from the upper end of said portion of said body. It vwill beobserved that. the lower portion of theburner-chamber 17 is reduced insize transversely from the apertures 25 to a point about midway betweenthe flange 22 and said apertures, that said apertures each extend fromthe chamber 17 laterally and upwardly substantially in a straight. linefrom the internal surface to the external surface of the downwardlyflaring portion 24; of the burner-body, and that said aperturestherefore communicate at their inner and lower ends with said chamberand are adapted to discharge laterally outwardly and upwardly at theirouter and upper ends and constitute lateral outlets of the chamber belowthe flange 22.

The burner-body B (see Figs. 2 and 3) is substantially uniform indiameter between the flange 22 and the upperend of the downwardlyflaring portion 24 of said body, Aandthe chamber 17 extends from lwithin said flaring portion vof said body upwardly above said flange.

The burner-body B (see Figs. 2 and 3) is provided, between the flange 22and the downwardly flaring portion 211 of said body,

with an annularly arranged series of lateral the outlets 26 that theoutlets 25 are arranged to discharge toward the discharge from theoutlets 26 and that, during the operation of the burner, the flamesissuing from the outlets 26 shall be intersecting rela tion, under saidflange, to the flames issuing from the outlets 25, so that said flangeshall serve as a baffle arranged to limit 'the ascent of said flamesbetween the circumferential edge of said fla-nge` and the burner-bodyand so that said body shall not have the portion thereof which extendsupwardly from said flange impinged against by said flames.

The burner-body B (see Fig. 2) comprises an upwardly flaring portion 27arranged over the flange 22 and also comprises a short down\\'ardlyflaring portion 28 larranged next above said upwardly flaring portion.Ity will be observed, therefore, that the downwardly flaring portion 2Sof said body is spaced upwardly from the flange 22, and that said flangemeasures more in. external diameter than any portion of the body abovesaid flange. 'The downwardly flaring' portion 28 of the burner-body see-Figs. 2 and 8) has an annularly arranged series of lateral apertures 29which are spaced circumferentiallyv of and con'ununicate with thechamber 17, and said apertures each extend substantially in a straightlinel from said chamber laterally and upwardly to the external surfaceof said flaring portion of said body. lt will bey observed, therefore,that vthe apertures 29 are adapted to discharge Vlaterally outwardly andupwardly at their outer and upper ends and form lateral out,- lets ofthe chamber 17. Y

The burner-body B (see Figs. 2 and 8) is provided, next above itsdownwardly flaring portion 28, with an annularly arranged series oflateral apertures 30 which are spaced upwardly from the outlets 29 ofthe chamber 17 and communicate at their inner ends with and are spacedcircumferentiallj-,f of said chamber and extend radially of said bodyand substantially horizontally from said chamber to the circumferencerofthe body. It will be observed, therefore, that the apertures 30constitute lateral outlets of the chamber 17, andthe outlets 29 are insuch spaced relationship to the outlets 3() that the outlets 29 arearranged to discharge toward the discharge from the outlets 30 so that,during the operation from the burner, the flames issuing from theoutlets 30 shall be in intersection. relation to the flames issuing fromthe outlets The burnerbody B extends above the outlets 30 of the chamber17 and is reduced in size transversely toward itsupper extremity.

@n the base A, adjacent its `outer circumferential edge (see Figs. 2, 3and 9), is removably mounted or seated a plate C preferably composed ofcast iron and surrounding the outer rib 16 of said base and saaeed thebase A and serving to preventl material horizontal displacement of saidplate on said from said rib all round the rib. v vThe plate C thereforemeasures more inl internal di- I ameter than the flange 22 and said rib16 measure in external diameter to permit lowering of said plate intoplace from above.

body B and arranged opposite and extend-` ing circumferentially of therear portion and forward portion respectively of and 'spaced somewhatfrom the circumferential edge of base.

' The plate C (see Figs. 2, 3 and 9) has holes 33 formed between thecircumferential edge of the base A and the outer circumference of saidplate, and said holes ex-r tend from the bottom to the top of said plateand serve to supply vair from under the plate to. the space surroundingthe burner-body between the flange 22 and the' downwardlyfiari'ngportion 24 of said body so as to adequately supportcombustionwhen llames are issuing from the outlets 25 and 26 of the chamber 17during the operation of theburner. Obviously, the plate C serves as abaflie which, while permitting the passage of air upwardly through theholes 33 from under the plate, does not permit the rush of an excessivesupply of air from below the burner to the flames issuing from theoutlets 25 and 26 of the chamber 17 dur-` ing the operation of theburner. Y

The baille-plate C also has several apertures 34 spaced from andcircumferentially of the burner-body B, as shown in ,dotted line in Fig.3, and one of said apertures is shown in solid lines in Fig. 7. Eachaperture 34 extends to the bottom of vthe plate C, as shown in Fig. 7,and communicates with an upwardly projecting and somewhat upwardlytapering tubular member Y 35 formed` on and at. the top of said plate,and saidaperture serves to supply air from under said plate to saidtubular member.

, The top surface of the flange 22 yof the burner-body B, next the outercircumferential edge of said flange (see Figs. 2 and 8) is overlappedVby a metal plate D preferably composed of cast iron. Said plate Dsurrounds the burner-body B and has an internal diameter which measuresless than the external diameter of the flange 22 and more than anyportion of said `body` `above said flange. The kplate D extends yfromthe flange 22 laterally outwardly andisprovided at its bottom with adownwardly projecting annular rib 36 arranged opposite and somewhatspaced from and surrounding the outer circumferential 'edge of saidflange. The

plate D constitutes a baille which1retardsfthe.l

ascent of products of combustion from the:` space between the bottombaffle-plate 'C and,`

the flange 22, and eachjtubu'lar membery 35. of said bottom balilefplate(see Figs. 7. and 8) extends into a hole 37 formed in and ex-r tendingvertically through the plate:V D.` The hol-es 34 in the baille-plate Dare large enough in ldiameter to causesaid plate D to lbe loose inrelation to the tubular members 3,5' of the baffle-plate C. Each tubularVmember35 (see'Fig.k 7) is externallyfprovided,ibe-1ow its. upperextremity, with anv upwardly facing shoulder 38 arranged to form a seatfor` the baille-plate, D and preferably. formed by the top of a flange39 which is formed on and externallv vof saidy member 35 and preferablyextends from said plate downwardly to th-e bottom baflle-plate C andthereby reinforces said member- 35. It will beobserved, therefore, thatthe bailleplate D not. only overlaps the flange 22 but is supported fromthe tubular members 35j and removable upwardly from said flange andtubular members.

Theburner-body B measures less in external diameter above theHbaille-plate D than said plate measures in internal di-v ameter topermit` the' applicationfof said plate from above saidbody. during theassemblage ofA the. parts and to permit-,removal of the plate D upwardlyfrom the flange 22 and tubular members 3 Y Y l The burner-body B (seeFig. 2) isVeX- terna-lly provided, above theoutlets 30 of the,burner-chamber 17, with an upwardly facingy and' substantiallylhorizontal annular shoulder 41 on which is removably mounts ed or seated'a metal plate E preferably composedn of cast iron and extending aroundloo l' saidy body, and said plate measures more in. internalr diameterthansaid body mea-v vC and the tubular members 35 of said plateconstitute meansl for supplyingfair from nnder said plate to the spaceextending around the burner-body B at the outlets 29 andB() Y of thechamber 17 and from the plate C to the plate D, so that air is` suppliedby said tubular ,members to the space between the plates D and E for thepurposel offade'- quately supporting combustion when flames are issuingfrom said outlets during: the operation of the burner. It will beobserved. therefore that; the.k top f plate. I E constitutes abaffle-which retards the ascent of products of combustion from the spacebetween said plate and the intermediate baffle-plate D f during theoperation of the burner.

The top baffle-plate E is provided, forward of the burner-body B, asshown in Fig. 1,"with an aperture 43 to permit the application of alighted match at said aperture for the purpose of conveniently lightingtherburner, but obviously the burner may be lit in any'approved'manner.V

The relative arrangement of the baflieplates C, D, and E is preferablysuch that Vthe space between the bottom baflie-plate C and theintermediate bafiie-plate D, and the space between .said intermediatebaffle-plate and the top bafiie-plate E,substantially` correspond insize vertically, andY said plates C, Dfand E preferably correspond inexternal contour and dimensions.

Each of the baffle-plates C, Dk and E has laterally and outwardly facingstraight and parallel side edges 45. Each baffle-plate is provided, ateach side edge 45 thereof, with a metal leaf 46 composed preferably ofcast iron and extending along and from end to.

end of said edge and pivotally connected, as `will hereinafter appear,to said plate in such a manner as to render said leaf capable of beingswung upwardly and toward the burner-body B. Each baffle-plate isprovided, at each of two points spaced longitudinally of each .side edge45 of the plate, with an upwardly projecting lug 47, and the leafV 46extending along said edge is provided, at its top and adjacent said lug,with'a member 48 which is pivoted to said lug by a substantiallyhorizontal pivotal pin 50 arranged longitudinally in relation to saidedge. The pivotal pins 50 of the connection between each leaf 46 and thebaffleplate provided with said leaf are in line endwise longitudinallyof said leaf, and said leaf normally abuts, at its inner longitudinaledge, as shown in Figs. 1, 2, 3 and 8, againstthe adjacent side edge 45of said plate. By the hereinbefore described construction it will beobserved that each leaf 46 of each baffle-plate is arranged to be swungupwardly from the position shown in Figs. 1, 2, 3, 4 and 8 into orinwardly beyond the upright position shown in Figs. 5 and 6, and thatsaid leaf, when it has been swung upwardly into said upright position,serves as aV handle for convenience in manipulating or handling thebaffle-plate and to enable the passage ofthe baffle-plate through adoorway having less width or dimensions than would be required were saidleaf not capable of being swung into said upright position. It will beobserved therefore that each leaf 46 of each baffle-plate also serves asan extension or enlargement of the baffle formed by said plate, andIwould here remark that said leaf preferably has linger-receiving holes51 for convenience in manipulating the leaf. f

In installing rmy improved burner in the combustion-chamber of afurnace, the base A and the burner-body B secured to said base are firstintroduced into said Vchamber and placed in the position required andsupported in any approved manner, and the pipe-section 14 may be appliedto said base preparatory to or after the placing of said base andattached burner-body in position in the furnace, and thereupon the plateC is passed into said combustion-chamber and over said body and thenlowered into place on the base A, whereupon the plate D is passed intosaid chamber and over the burner-body and lowered into place in rela!tion to the fiange 22 and tubular members 35, and after the applicationof said plate D the plate E is mounted on the burner-body.

Not unimportant tol a highly successful operation of my improved burner,and to prevent quivering or unsteadiness of 'the' fiames issuing fromthe burner during its operation, is the extension of the fuel-receivingchamber 17 above the uppermost outlets 30 of said chamber and preferablyupwardly into the upper portion ofthe body B to a point above the topbathe-plate E, and I would here remark that IV have, attained highlysatisfactory results inthe operationV of burner embodying my inventionand having said` chamber gradually reduced in size transverselysubstantially from said uppermost outlets to the upper extremity of thechamber, as shown in Fig. 2.
